CHART Filed Jan. 17, 1930 3 Sheets-Sheet 3 By @TMH Patented Jan. 27, 1931 PATENT OFFICE CHARLES M. DAVENPORT, OF RICHMOND, VIRGINIA CHART Application filed January 17, 1930. Serial N'o. 421,579.

This invention relates to charts and more particularly to that type of mechanical chart having indicator-y means for use in comparison with a scale.

The object of this invention is to provide a chart of the kind above described which graphically displays comparative facts in an intelligent and readily understood manner.

Another object of this invention resides in the provision of a chart of the kind described in which a series of transparent containers `are used toreceive fiuent indicatory material and separatevalve controlled reservoirs for each oi the containers.

A still further object of this invention is to provide a Vvalve-controlled means for draining the transparent containers of the indicatory material and a guard locking means for both the reservoir and the draining valves to prevent unauthorized operation of the same. l

With these and other objects in view this invention consists of certain novel combinations and arrangement of parts as will be fully set forth in the following description and illustrated in the accompanying drawings wherein Figure 1 is a front elevation, `partly 1n section;

Figure 2 is an enlarged front elevatlon of the upper portion of the device W1th the ,f prairlA casing removed showing the valve guard in one positlon;

Figure 3 is a view similar to Figure 2 with the valve guard 1n another positlon;

Figure 4 is a view looking down on the` top of the chart with the reservoir lid raised; Figure 5 is a section takenfon line 5 5 on Figure 1;

Figure 6 is a section taken on line 6 6 on Figure 1;

. Figure 7 is a fragmentary perspective of one corner of the chart showing valve guard actuating means;

Figure 8 is a section taken on line 8 8 of Figure 7 and 1 Figure 9 is a fragmentary perspective of one end of the draining receptacle.

Referring to the parts by reference numerterial having side pieces 11, running the entire length thereof and what will be termed 1an upper partition 12 and a lower partition 13 are placed transversely across the back 10 adjacent the upper and lower edges respectively thereof. Suitable yfacing strips 14 are secured to the pieces 11 and partitions 12 and 13 by fastening means 15. The pieces 11 and partitions 12 and 13 are grooved to removably receive a chart card 16 and a glass covering 17. A series of vertically disposed openings 18 and 19 are provided in the partitions 12 and 13, respectively, and connecting these openings are a series of transparent containers or tubes 20. These tubes are securely retained in place by means of the gasketsY 21 which surround that portion of the tubes in the partitions. By reference to Figure 5 it will be seen that the tubes 2() are thus securely held in place between the glass covering 17 and the chart card 16. These tubes 2O are grouped in pairs in the embodiment of my invention illustrated, but any grouping or arrangementL of the same may be had to more clearly and graphically discover 10 and having a series of partitions 2:2 a.;

forming a separate reservoir 22d-for each ot the transparent tubes 20. Each reservoir 221 has one of the openings 18 in communication with one of. the tubes 20. Passing transversely through the upper and lower partitions 12 and 13 and intersecting each opening 18 and 19, respectively, in these partitions are a plurality of rotatable valves 24, each of which consists of an elongated body having a port 25 and an instrument engagement head 26. The opposite end of the valve from that of the head 26 is wrapped with a spring 27 to retain the port of the same in proper position relative to the openings 18 or 19. but in no Way affects the rotation of the valve. For the purpose of better description. the valves in the upper partition 12 will hereafter be referred to as the filling valves, While those in the lower partition the' vdraining valves. lA draining receptacle 28 is releasvably secured beneath the lovver partition 13 by means of the Wing nuts 29.

From the foregoing it Will be seen that the flow ot fluent material from the reservoirs Q3 into the transparent containers or tubes 2O is controlled by the filling valves 2st by rotatingthe same to align the ports therein with the openings 1S, the draining valves in the lo'iver partition 1 3 at this time being set to prevent the fion ot material ont of the tubes 2O into the draii'iing container'28. ln this manner the uent indicatory material 30 will be allowed to low into the containers or tubes 20 until the proper height is reached. It for some reason more material 30 is allowed to flow intov a certain tube the draining valve for that tube is rotated to4 align its port with an opening. 19 and the proper amount of materialBO- 'allowed to pass into the draining 'receptacle 28, These draining valves are obviously also used. to drain the tubes 20 for any reason.

A valve guard means is provided for both the iilling and draining valves. he construction ot the guard means for each set ot valves is the same, therefore, the description of onev Will suilice. A guard strip 31 having a series of apertures 32 is slidable over the valve heads 26 by means ot an endless carrier 3- trained over sheaves 34j This endless carrier 33 has a. resilient element 35 in the same and in connection vwith the strip 31 to pro vide the proper friction on the sheaves Bfl. A pair of key-receiving sockets 36 are found in the sheaves 34 to receive the projections Si" of an operating key 38. Covering' this strip 31 is acasing 39 having a series or apertures 4l() iormed therein. valve heads for operation it is necessary to move the guard strip 31, by rotating the sheave 531i Avvith the key 38 to such an extent only to align the proper apertures 32 and 40 ith the desired valve to allow for 'the passing oiA an instrument through the casing 39 and strip 3l for engagement with the ralvc head to rotate the same.

The present einbodiinent ot this invention shoivn for use as a chart to indicate the monthly sales, production or attendance with a comparative indication together with an accumnlative and accumulative comparison indication. One specific use is for indication ot the yearly sales of an automotive agency. Two tubes are provided fo each month. ln

' one tube fluent indicatory material (preferably colored sand)rione color Would be ted until the proper height Was reached on the chart card to indicate the number ot cars,

parts, or cost of the same, the agency was allotted the manufacturer While in the tube next adjacent thereto a fluent material cfa color contrastig-that of the first would be fed as the sales' were made. The accumulated sales, as Well as the yearly allotment would be indicated by the material in the .not a'.

To gain access to the tubes labeled ACU. It being obvious that the chart card readings for use in comparison With the material in the last mentioned tubes would be different 'from the remainder of the card, in vtact to contrast the yearly or accumulative indication, that portion of the chart card scale usedV withA the yearly accumulative tubes should be ot a different color from those used tor the monthly indications.

Thus the number off cars or parts sold, or money received from the sales for one month in comparison with the allotment for that month, as well as the accumulative sales in comparison With/the yearly allotment, will be graphically indicated by the heights of the dil'lerei'it colored materials in .the tubes against the scale on the chart card.

lli-om the foregoing it is evident that a mechanical chart has been providedl that makes .no use ot'bloclrs, pegs`,vtapes or other well k-noivn means and methods for graphically displaying comparative facts, but instead provides a chart using fluent indicatory material, the flow of which into transparent retaining receptaclesY is valved controlled. rlille invention contemplates the use of said means in a chart for the graphic display of acts Whether they be sales, attendance, temrature records or any other facts capable graphic display, l aving thus described the invention it 'lesired to limit the same to the embodinien.- shown and described, but Vto cover all such as 'properly come within the scope of the appended claims.
